3260BWayne Kerr 3260B 测试分析仪
Wayne Kerr 公司的WK-3260B测试分析仪,除基本的LCR及阻抗等测试功能外,还具备直流偏压和圈比测试,是一款偏重于变压器等磁性元件而设计的.由于测试精度高,功能多,方便操作,目前绝大多数客户都采用这种设备.相对于HP的测试仪器来讲,操作方便,易上手,精度高,更受工程师喜爱.配备的DC BIAS大可到125A.
At the design stage of component development it is vitally important to understand how the component performs under different operating conditions. This might include operation at diverse frequencies, AC drive levels or DC bias currents.The 3260B Precision Magnetics Analyzer can plot any of the measurement functions, such as inductance (L) or impedance (Z), (including secondary term) against frequency, AC drive level or DC bias current.
Frequency sweeps within the range 20 Hz to 3 MHz can be selected. There is a choice of either linear or logarithmic frequency displays.3260B is especially suitable for measuring parameters on telecom transformers.The selected measurement parameter and its secondary value are presented graphically. AC drive levels can be set between 1 mV and 10 V. DC bias current can be set from 1 mA to 1 A internally. Using external 3265B 25 A DC Bias Units bias currents can be set to a maximum of 125 A.
Measure Insertion Loss and Return Loss on telecom transformersWith the dramatic growth of PCs connected to the telephone system for Internet access has come the requirement to measure Insertion Loss (IL) and Return Loss (RL) of line matching transformers.The 3260B Precision Magnetics Analyzer not only measures IL and RL has this capability. but the instrument also allows the user to enter the values for terminating resistance or impedance, if complex, and to select a damped network or blocking capacitor if required.Specification summary
